SPECIFICATION forming part of Letters Patent No. 4, 39, dated January 1, 1 01 Application filedMay 18, 1900. Serial No. 17,155- (No model.)

To all whom, it nuty concern:

3e it known that I, ANDRE DEBUSSY, of Paris, France, have invented a new and useful Folding Attachment for Embroidering- 5 Machines, which is fully set forth in the following specification.

The object of the present invention is an improvement in plaiting or folding apparatus applicable to sewing-machines, but princi- 1o pally useful when applied to universal embroidering-maohines in order to produce the plaiting or folding of ribbons, fiat braids, or similar articles in all directions in conformity with the universal feed of the machine. The

following is a description of this mechanism when applied to such universal-feed embroidering-machines, reference being made to the accompanying drawings, wherein- Figures 1 to 6, inclusive, are part elevation and se ctional views of the folding mechanism, showing successive positions of the parts in the operation thereof. Figs. 7 and 8 are perspective views, Fig. 9 a sectional view, and Fig. 10 a plan view,of parts of the mechanism.

Fig. 11 is an elevation of the head of a machine embodying the invention.

The mechanism is mounted upon the nipple Q of the machine, and it is composed of, first, a block R. (represented on an enlarged scale at Figs. 7 and 9,) which can slide vertically on the nipple Q, but which turns with said nipple as a flat side of it bears against a corresponding flat side of the opening through the nipple Q, as represented at Fig. 7; second, a folding shoe or guide P, Figs. 8, 9, and 10,which is provided with grooves 2, into which the tongues 3 of block R enter, so that the shoe P can slide horizontally upon block R and can also participate in its vertical and in its turning mo- 0 tion; third, a spring S, which is secured to the hub X, which latter can be turned upon the fixed tube WV by means of the crank-handle of the machine, while the nipple-tube U plays within the tube W, the lower part of spring S working in a slot F, Figs. 8, 9, and

10, of the shoe P in order to impart a horizontal motion to said shoe P at the right moment, and, fourth, a ring 0, which is secured to the nipple-tube U and which communicates the motion to spring S at a certain moment.

The operation of this mechanism is as follows: In Fig. l the nipple Q, with its apparatus, is at its highest. position. The ribbon at, which is to be folded, passes through the central tube of the machine down into the folding shoe or guide P between the bar A and the serrated plate B, (represented at Figs. 8, 9, and 10,) thence between the bar 0 and the two teeth D, which are secured to the inner sides of the folding-guide P, and thence 6o through the inclined slit G down to the cloth.

In Figs. 2 and 3 the nipple Q, with the entire mechanism, has commenced its downward motion and produces thus the commencement of the fold, owing to the fact that the ribbon a, being held firmly by bar A, serrated plate B, and teeth D, cannot yield in an upward direction. The nipple and its apparatus descend,then,farther to the position represented at Fig. 4:. In this position the ring 0 arrives below the incline b of spring S, whereby the latter pushes the shoe P to the left and not only continues in forming the fold, but also brings the fold directly below the needle, as represented at Figs. 4 and 9. This latter operation is obtained with great accuracy, as the motion of the folding-shoe to the left is completely stopped by the bar 0 coming in contact with the lower part of the nipple Q. The nipple Q now still continues its downward motion,and the entire apparatus arrives at its lowest position, Fig. 5, where the shoe P presses the fold upon the material or upon the cloth-plate and holds it firmly. The nee dle, which thus far has not followed the descending motion of the nipple, now descends and stitches through the fold and through the material and sews it thereon, Fig. 6. After this the nipple Q commences to rise again, but the shoe P remains still pressed upon the material by the action of the spring (Z until the projection M of the nipple Q, Fig.

7, raises the shoe and the entire apparatus again to the position represented at Fig. 1. Similarly, as in braiding-work, this folding or braiding work can also be produced Without being formed on and attached to the fabric or cloth. Fig. 11 represents the head of a universal embroidering-machine provided with this folding apparatus, which thus turns in I00 conformity with the universal feed by means of the crank-handle of the machine. The

central tube 9 is turned by the crank-handle by means of shaft h and pinions iand 7c, and as the tubeg is coupled to the nipple-tube U they both turn together, and thus cause the entire apparatus to be governed by the crankhandle of the machine. The spring S is secured to the hub X of the wheel 25, which is equally governed by the crank-handle of the machine by means of wheels 0', q, p, 0, and n and shaft h.

I claim 1. In a sewing or embroidering machine the combination with a sewing-needle and means for operating the same, and a reciprocatory nipple and means for operating the same independently of the movements of the needle, of a laterally-movable guide for ribbon, braid or the like reciprocated by the nipple, and means for imparting lateral movement to said guide whereby the ribbon, braid or the like is formed in folds beneath the sewing-needle.

2. In a sewing or embroidering machine the combination with a sewing-needle and means for operating the same, and a reciprocatory nipple and means for operating the same independently of the movements of the needle, of a guide for ribbon, braid or the like movable laterally with reference to the nipple but mounted on the'same so as to partake of its reciprocatory movements, and means for imparting lateral movement to said guide whereby the descending and lateral movements of the guide act to form the ribbon in folds beneath the sewing-needle,

3. In a sewing or embroidering machine,the combination with a sewing-needle and means for operating the same, and a reciprocatory nipple and means for operating the same, of a block-carried by the nipple and movable therewith, a guide for ribbon, braid or the like mounted to move laterally on the block, means for imparting reciprocatory movement to said guide whereby it acts to form the ribbon in folds beneath the sewing-needle.

4. Inasewingorembroideringmachine,the combination with a sewing-needle and means for operating the same, and a vertically-reciprocatory nipple and means for operating the same, of a block carried by the nipple and through which the latter loosely engages, a guide for ribbon, braid or the like mounted to move laterally on the block and normally projecting below the nipple, and means for imparting lateral reciprocatory movement to the guide during its vertical movement with the nipple, whereby the ribbon is formed and pressed in folds against the fabric beneath the sewing-needle.

5. In a sewing orembroidering machine, the combination with a sewing-needle and means for operating the same, and a vertically-reciprocatory nipple and means for operating the same, of a block having an opening therethrough through which the nipple loosely engages, a projection on the nipple beneath the block and-against which the latter normally rests, a guide for ribbon, braid or the like movable laterally on the block and normally projecting beneath the nipple, and means for r imparting lateral reciprocatory movement to the guide during its vertical movement with V the nipple whereby the ribbon is formed and pressed in folds against the fabric beneath the sewing-needle.

6. In a sewing orembroidering machine, the combination with a sewing-needle and means for operating the same, anda reciprocatory' nipple and means for operating the same independently of the movements of the needle, of a laterally-m ovable guide for ribbon, braid or the like, reciprocated by the nipple, means for imparting lateral movement to said guide whereby the ribbon is formed in folds beneath the sewing-needle, and means for turning the nipple and guide to effect universal feed of the parts without interfering with the other operations thereof.
